Hi Philippe,

I was trying your suggestions for some time. I am still stuck with booting 
problem.

Below are my steps:


Step 1> sudo dd if=u-boot.bin of=/dev/sdb bs=512 seek=2 skip=2 conv=fsync
Step 2> sudo dd if=uImage of=/dev/sdb bs=512 seek=2048 conv=fsync
Step 3> sudo bzcat ivi-XYZ.raw | sudo dd of=/dev/sdX

Now, after step 3, I am not able to get the screen, it boots and loads the 
kernel, but soon gives kernel panic error: No filesystem could mount root, 
tried: ext3 ext2 ext4 vfat msdos iso9660

Other way I tried was after cleaning sdcard, I repeat step 1 and step 2 and 
below step3:


Step 3> sudo bmaptool copy 
http://download.tizen.org/snapshots/.../ivi-XYZ.raw.bz2 /dev/sdX

Here I don't even get the boot-sequence, so it is something I am missing here. 
I think bmaptool also, does the same thing as dd, but results are different.

You boot.cmd has below commands:
fatload mmc 0 0x46000000 uImage ;
fatload mmc 0 0x49000000 sun7i-a20-olinuxino-micro.dtb

So, where do you place these uImage and .dtb files. Are they locally present in 
some folder or in sdcard?

Thanks,
Jay
